Featuring advanced aerodynamic design measures such as Flow Acceleration Channels and Noctua's AAO frame, the NF-A4x20 5V is a dedicated 5V version of Noctua's highly optimised, premium quality quiet 40x20mm fan. Smooth Commutation Drive technology and Noctua's reference class SSO2 bearings guarantee superb running smoothness and excellent long-term stability. Topped off with modular cabling, the OmniJoin Adaptor Set and 6 years manufacturer's warranty, the NF-A4x20 5V is a premium choice for demanding 5V applications. Being a 5V fan, the NF-A4x20 5V cannot be run at 12V and will be damaged when used with typical 12V power sources such as PC motherboard fan headers.
